Be it lrnoivnthat l? CHARLES C. Hnnnnn'r, a citizen of the UnitedStates., Yand a resident of San Jose,Y in the county of Santa Clara andState of California, have invented certain neu7 and usefullinproveinents in @feter Circulators7 of 1vhich the folloiving is aspecification.

This invention relates particularly toV a device to he inserted in theWater cooling systein of an internalconibustion engine on an automobilefor the purpose of imparting a Apositive cireulationof the vvaterthereinas Well as operating a fan used in connection therewith.

lt is one object of myL invention to provide a device of the characterindicated that perniits the free flow of Water and steam in anunobstructed path of travel frein the engine to the radiator of thesystem. v

lt is another object to provide .a device or" the character indicatedthat is equipped-k ivith a purnp in suoli a manner as to accelerate thespeed ofthe Water flowing from engine to radiator. i

lt is a still further object to provide device of the characterindicated wherein the puinp driving niechanisin is adjustable relativeto the Water conduit therethrough whereby the driving belt rnay betightened at will Without shifting the device as a Whole relative to theengine.

lt is a still Vfurther object ofniy invention to provide a device of thecharacter here-` inhefore set forth that will he siinple in forni andconstruction, economical to inanufacture, highly elicient in itspractical application and provided With a lubricating means so arrangedas to properly luhricate moving parts Without driving the lubricant intothe Water passage.

ln the drawing Figure 1 is a rear elevation of my irnproved pump.

Figure 2 is a section on 2-2 of Figure 1.`

Figure 3 is a side elevation of a. portion of the device. parts beingbroken away.

Figure e is a modified forni of a portion of the invention,

Referring niore particularly to the drauing, 1 indicates an elementprovided with a conduit 2 having a flange at 3 for attaching the saineto an engine shoivn in partat el and fitted .vith apipe shown in part at5 leading to a radiator not shown.

1. M 1 1 LW: is tuoulai part 6 contracted at its upperL nnd to foin anoiilice i it is a sleeve having a loiver portion 9 of larger diameter toengage the l iver portion of part 6 and forming a shoulder 10,' therebyforming with art 6 a chamber 11. rlhe upper end of chaniber 11 is Closedofi by ineans of a Washer 12,Vv it 8 is a conical sheet-metal elernentpressed into orifice 7 and'forniing With Washer 12 a chaniher 13 filledwith packing 18a. ,l-nseted between shoulder 10 and ivasher'12 is aspring le which exerts pressure on sleeve 8 tending to force it down-Wardly and out of tubular part 6. nirranged on part 6 and extendinglaterally therefroni is a lug .15 having an orifice 15 therein. 8 ies asimilar lug 17 tapped as At 19 is a bolt passing n Y orifice16 andengaging' tapped lug construction lirnits the outward inoveniei ofsleeve ,8 under pressure froin spring and yet permits adjustment of theparts as occasion may require. Part 6 is split at 2O and the engagementof the part with sleeve 8 is adjusted by ineans of a holt 21 passino"through orifice 22 in lug 23 on one side of the split 20 and engagingthe tapped part 24- of lug25 of the split 20.

rlhe lower end of part 9 of sleeve 8 is fitted with a bearing 216Vthereby formingn` 2.7 therein. ln bearing 26 is mounted a shaft 26acarrying a bevel gear 28 at its lower end and a propeller V29 at itsupper end, the latter beingv heldin place by a Washer SO and nut 31 andoccupying suhstantially rhe center of conduit 2.

Meshing with gear 28 is a bevel gear 32 niounted on shaft 33 revolvingin bearings 3ft-35. Bearing 34e is mounted in a threaded closure 36, andbearing 35 is formed in a laterally extending arin 3?. rlhisconstruction foi-nis a chainber 38 around gears 28 32, the saine beingfilled with grease under pressure through grease cup 39. Shaft 33carries a driving pulley and fan not shown, the saine being mounted uponpart 4r() which is inouuted upon shaft 33 to revolve therewith.

llt/hen the device is operatively mounted upon a machine and the shaft'33 is revolver through the usualheit and 'pulley connections to theeranl shaft, the propeller is on the other side revolved through theinediuni of gears 3L-2S and shaft 26a, thereby boosting the Water andsteam flow and causing a positive circulation of the same through thecooling system. These parts are so arranged that full advantage is takenof the natural tendency of heated water and steam to rise, the pumpmerely encouraging that tendency to secure the lrequired rapidity ofmotion.

The chamber 38 being filled with grease under pressure,the revolvingparts gradually permit the same to work through bean ing 26 into chamber27, this chamber in time becoming filled or at least partially so, sothat sufficient lubricant finds its way into sleeve 8 around shaft 26ato keep it properly lubricated. By this construction all working partsare thoroughly lubricated yet by providing chamber 27 the lubricant isfed around shaft 26'DL in sleeve 8 without pressure and consequently nogrease is forced into the circulating water.

If, during the operation of the device, the operating belt becomes looseit may be tightened up by merely forcing parts 8 to Ll() upward againstthe outward pressure of spring 14e until the belt has been sufficientlytightened. The bolt 19 is then screwed up to hold the parts in their newpositions, T his adjustment is simple and effective and does not disturbthe seal between the device and engine Ll as is now the case with knownconstructions, the spring lat effectively keeping the packing 13a tight.

In Figure l a modified construction is shown wherein the sleeve 8extends through the orifice 7 and the packing 13@L contacts with thesleeve instead of the shaft as hereinbefore described.

lt is to be understood, of course, that while I have herein disclosedone specific embodiment of my invention, changes in form, construction,materials and method of operation may be made within the scope of theappended claims.

1. A device of the character indicated ing therewith, a sleeve slidablyengaging said tubular portion and passing into said conduit, a resilientmeans inserted between said sleeve and body portion normally urging thesame in opposite directions,'means for limiting the action of saidresilientmeans, and a shaft revolubly mounted in said sle-eve and havinga propeller mounted thereon.

3. A device of the character indicated comprising a body portion havinga conduit passing therethrough, a tubular portion eX- tending therefromand having a restricted communication therewith, a sleeve slidablymounted therein and extending into said conduit, a shaft revolublymounted in said sleeve, agrease chamber arranged in'said sleeve aboutsaid shaft, a chamber arranged in said tubular portion encompassing aportion of said sleeve, a resilient element arranged in said secondchamber to urge said tubular portion and sleeve in opposite directions,means for limiting the action-of said resilient clement, and a propellermounted on said shaft in said conduit.

Ll. A device of the character indicated comprising a body portion havinga conduit passing therethrough, a propeller revolubly and slidablymounted in said conduit, a driving shaft geared to said propeller atright angles thereto, and means for adjusting said propeller and drivingshaft relative to said body portion.
